CALENDERING OR IRONING *MACHINE Application tiled DecemberV 5, 1923,Serial No. 678,716, anden Great Britain December 12, 1922.

This my invention has for its object improvements in the means ofcaiendering or ironing wool `fabrics and the like, and in folding undbaling the same. more particularly those of a tubular forni knit in acontinuous length, so that the fabric has its longitudinal wales orthreads quite straight corresiionding with the edges of the, fabric, andthe horizontal courses or threads also traight andat right angles to theedges., in such a manner that the fabric passes into and through themachine` to the folding` or baling appliances withoutdeformation of thelongitudinal wales and horizontal courses.

To attain this end, the machine has two vertical housings suitably fixedone at each side of the base-plate, and the housings are formed to carrytwo or preferably three pairs of calendering cylinders, as well as twoor more pairs of auxiliary guide rollers for guiding the fabric in aproper form to the calendering cylinders.

All the calendering cylinders are driven by suitable Igearing from adriving shaft which is actuated by an electric motor, or by belting orother suitable means. One vcalendering cylinderl of each pair has itsshaft rotating at each end in suitable bearings which are stationary inthe housings, and the other cylinder of each pair has its shaft turningvinbearings which can be adjusted ho 1izontally in the housings bysuitable screws, gearing and rhandwheel to each, all in such a mannerthat the fabric may pass through the calendering cylinders under adesired pressure. The shafts of .the calendering cylinders at one sideof the machine arerof such a length that gear wheels with specially longteeth may be fixed thereon, so as to alwaysvensure being properly gearedto each other when the movable bearings are moved inwards or outwards.

T he calendering cylinders and their shafts are formed hollow, so thatthe cylinders can be heated by steam,rgas, or other suitable means.

At the top of the machine is a suitably driven roller, over which theAfabric passes into the machine over an expanding gauge, and over whichthe fabric is guided by several pairs of vertical and horizontal guiderollers, all positively driven by gearing or other suitable means fromthe driving shaft. These guide rollers serve the purpose of assistingthe fabric to pass between the calendering cylinders in the lower partof the `machine without.deformation of the fabric cases may be fittedwith guide rollers posi-v Y tively driven by gearing from the drivingsnaft 1n a lilrc manner tothe upper gauge.

From thence the fabric passes dr'iwnwardsv and through or between one ormore other pairs of calendering cylindersall in such a manner that thefabric passes through all these cylinders without deformation of thethreads as named above, and at the same time giving the?y required'ironing surface thereto.

After leaving the calendering cylinders the fabric is baled', or woundupon a horizontal roller at the base of the machine, and suitably driventherefrom. Or in some cases it may be delivered in a folded state bysuitable oscillating mechanism actuated by the machine. n i

The ca-lendering cylinders may in some cases be covered with apreparation to improve the ironing of the fabric passing through them.

Also, when the machine is driven belt-- ing, electric motor or the like,a ysuitable friction clutch may be fitted on the driving gear so. thatthe operator may have perfect control of the machine,

I 'att-ain. these objects by the mechanism illustrated in theaccompanying drawings, in which z-f F iggl is a front elevation of myimproved calendering andbaling machine.

Figure 2 is an end elevation of the same machine, when looking at theright hand side as shown on Figure l.

Figure 3 is a plan of the same machine.

Figure 4 is a front elevation of the top eX- pandiloleI gauge andcarrying carriages.

Figure 5 is an end elevation of the same gauge when looking at the righthand side as shown on Figure 4.

Figure 6 is a plan of the-same gauge.

Figure 7 is a frontelevation of the second or lower gauge.

Figure 8 is an end elevation of the same gauge when looking at the righthand side as shown on Figure 7 Fig. 9 is vertical section on broken line9-9 Fig. l, showing the position of worm wheel casing E in dot and dashlines and i? l0 is a` vertical section on line lO-lO Fig. l.

Similar letters of reference refer to similar pa s throughout theseveral views.

ln these viewsl A, A represents the vertical housings each fixed one ateach side of the baseplat-e B, the three pairs of calendering cylindersare represented by C, C, and the four pairs of auxiliary guide rollersby D, D, these are for guiding the fabric in a suitable form to thecalendering cylinders C, C.

The calendering cylinders C, C are driven by gearings G, G from thedriving shaft G2 actuated through a worm wheel and worm (not shown) incasing lll-by the electric motor E, or by any other suitable drivingmeans. n

The hollow shafts-one of cach pair-of the calendering cylinders C, Crotate at each end in stationary bearings l?, F Xed on the housings A,A, and the shafts of the other cylinder of each pair turn in slidingbearings F1, which can be adjusted horizontally by screws having springcushions by the handwheels H, H through the bevel gearing Hl, so thatany desired pressure may be brought to bear on the fabric passingbetween the calendering cylinders C, C. Gear wheels Gl with speciallylong teeth are fixed on the calendering cylinder shafts at one side, soas to ensure the gear wheels G, G always being properly geared into eachother when the bearings Fl arc moved to and fro.

The calendering cylinders C, C are heated by steam orother suitablemeans passing through the pipes J, J, and the stulling boxes Jl on thehollow shafts of the calendering cylinders, and thence through thesecylinders and out by the outlet pipes J2.

The fabric is first passed over the roller Dl, and thence over theroller D11 atthe top of the machine to the upper expandible gauge l overwhich it passes without deformation of the fabric through the top pairof calendering cylinders C, then to the sccond or lower expandible gaugeKl, passing over same-without deformation-and thence between the secondand third pairs of calendering cylinders C, C to the baling roller ifsuitably driven from the machine, or to a folding appliance as desired.The folding appliance is shown by N, which consists of arms N, N pivotedfrom the machine at Nl and fitted with guide rollers T, T for lfoldingappliance are preferably driven from the machine by belt or gearing asshown on the drawings.

The top expandible gauge K is expanded or contracted at will on theguide bars L, L, and the two halves are held in place by the ratchet andpawl L1. The gauge K'is carried between the carriages l), l), which arefitted with the rollers R, R driven in a positive manner by the gearingS, S from the drivingV shaft Q1, which has a lreyway formed therein thefull length between the bearings in the housings for actuating the bevelgear wheels S1 sliding thereon.` The gauge carriages are carried on theguideV bars Q, Q., and the two halves of the eX- pandible gauge'K areadjusted to any desired width bythe rightand left hand screw bar U andhand spoke wheel Ul.

The second or lower erpandible vgauge Kl is also expanded or contractedat will and by hand on the guide bars L, L and in the same manner as thegauge K., the two halves being held in position by the ratchet and pawlLl. on the halves of the expandible gauges to assist the passage of thefabric more easilyl over the same. Y Y

lifhat l do claim as my invention, and desire to secure by LettersPatent, is

l. ln a calendering machine, in combination, pairs of superimposedcalendering cylinders, housings, bearings on said housings for saidcylinders, expandible gauges arranged one above the other, adjustablecarriages carrying the uppermost gauge, and positively driven guiderollers on the carriages forthe purpose substantially as hereindescribed.

2. In a calendering machine, the combin nation of eXpandible gauges forinsertion intoy tubular material, carriages provided with positivelydriven guide` rollers, one of said gauges being supported by saidcarriages, pairs of superimposed calendering cylinders, shafts for saidcylinders, bearings for said shafts, and housings on whichsaid bearingsare provided substantially for the purpose specified.

In testimony whereof I have signed my name to this specification.
